#### Transcript of Baking

-Students in grades 3-6 can benefit from learning about the central role that math has in cooking

Thinking
"Through"
Mathematics
I choose baking because...
I enjoy baking
-Learning about the math in baking interests me and will make me become a more successful baker

An abundance of mathematical ideas are involved in even the most effortless of recipes
-People in general seem to overlook the math involved in every day activities like baking
Types of Math
Thinking
"through"
math is the wonder of mathematics.

Multiplying Whole Numbers
Temperature
-Converting Celsius to Fahrenheit
Time
-Understanding secs, mins, & hours
Multiplication
-Doubling, Tripling... a recipe (entails multiplying whole numbers & fractions)
-Multiplying measurements when you don't have the exact measurement you need
Ratios
-Comparing amount of one ingredient to another (if you don't have enough of an ingredient for a recipe)
Addition
-Realizing that the ingredients that you add to a recipe will equal a certain amount of food altogether
Subtraction
-Subtracting the amount of food eaten to find out what's left
-Eliminating ingredients that you don't have or ran out of

Fractions
-Knowing certain measurements are part of a whole (ex. 1/4 cup)
Measurement
-Converting measurements (ex. tsp to tbl spoon)
Dividing
-Sharing baking
"OK class, today we're going to learn how to
combine quantities to obtain their product
"
Physical materials or manipulatives have become enormously popular as tools for teaching mathematics. These tools assist students in understanding & retaining mathematical concepts (Van de Walle, Folk, Karp, Bay-Williams, 2011).
Concrete Objects
Lego blocks
Bowls of beans
Pictures & Diagrams
SURPRISE!
When baking, a person must have many accessible mathematical ideas and concepts available at their fingertips:
"The more ways that children are given to think about and test an emerging idea, the better chance they will correctly form and integrate it into a rich web of concepts" (Van de Walle, Folk, Karp, Bay-Williams, 2011, p.25).

-I've always thought that I was cursed with being unable to excel at math
-Recently, I learned that baking is extremely complex in terms of math
-I was surprised to discover that I indeed do have some mathematical proficiencies and that I can use my knowledge of mathematics in cooking to understand a variety of mathematical concepts regularly taught in school

Informal (aka Everyday) Language
-Most commonly used symbols in multiplication:
-Brackets are sometimes used to indicate order of operations when multiplication isn't the only type of mathematics present:
-Sometimes multiplication can be seen as written with a raised dot or a star (asterisk) sign:

or
seen more in older grades

The math in baking will advance students thinking in the following ways:

Conceptual understanding
Visualization
Mathematical Reasoning
Mental Mathematics & Estimation
Flexible thinking

(Liedtke, 2010, p. 16)

Grades Explored
-Multiplication covered in elementary
-Students must have knowledge of multiplying whole numbers before moving onto multiplying fractions
-Cooking requires the use of multiplication skills and strategies

"Would someone please tell me what '
five times five' equals
?"
"Once you've obtained the answer to that question, try
multiplying five by six
".
"If all three of the guests bring one food item there will be
triple the amount

of food at the gathering.
"I'm going to
take
one dessert from each of the four plates,
so that I'll have four desserts to eat
altogether
".
Rationale
"I'll make
twice as many
cookies if I
double
the recipe".
(In class notes, 2014)
"You
always
want to use a variety of objects when teaching mathematics" (Thom, 2014).

A recipe call for
18 mL
of food coloring, however you only have a
3 mL
dropper. The baker must use the dropper
6 times
:
By viewing pictures and diagrams, students will begin seeing number as more than just objects
